Will JonesandClaude Opus 5.5 2c2bb9a974 feat(python): pass merge_insert sources as scannables
Python's `execute_merge_insert` now takes a `PyScannable` (like `add()`),
and the source collection threshold is exposed as a
`source_collect_threshold_bytes` kwarg on `execute()` and a
`merge_insert_source_collect_threshold_bytes` connection option.

Node passes the decoded IPC batches as a `Vec<RecordBatch>`, so the
merge join sees their exact row count.

LanceDB JavaScript SDK

A JavaScript library for LanceDB.

Installation

npm install @lancedb/lancedb

This will download the appropriate native library for your platform. We currently support:

  • Linux (x86_64 and aarch64 on glibc and musl)
  • MacOS (Intel and ARM/M1/M2)
  • Windows (x86_64 and aarch64)

Usage

Basic Example

import * as lancedb from "@lancedb/lancedb";
const db = await lancedb.connect("data/sample-lancedb");
const table = await db.createTable("my_table", [
  { id: 1, vector: [0.1, 1.0], item: "foo", price: 10.0 },
  { id: 2, vector: [3.9, 0.5], item: "bar", price: 20.0 },
]);
const results = await table.vectorSearch([0.1, 0.3]).limit(20).toArray();
console.log(results);

The quickstart contains more complete examples.
